PS5 [resolved] Pfalz Runner Scenario Unfinishable

At begin of this scenario on Ludwigsbahn route whit the green E94, when set the loco for departure the game said "wait for the Main Reservor to charge" but i've waited 10 minutes and the brake pressure is still at zero even if i have followed game instruction

 

Have you activated the air compressor on the panel to your left ?

 

Ok this time i solved it, i've done nothing new from last attemps
